Embodiment Construction

[0065] Below in conjunction with specific embodiment and appended Figures 1 to 20 The technical solution of the present invention is described further, but the present invention is not limited to the following examples.

[0066] Such as Figures 10 to 15 As shown, a rhombic octahedron that can be locally scaled, the first deformation surface 10 is composed of the first rod 10-1 of the first deformation surface, the second rod 10-2 of the first deformation surface, and the third rod 10 of the first deformation surface -3 and the fourth rod 10-4 on the first deformation surface, one end of the first rod 10-1 on the first deformation surface and one end of the second rod 10-2 on the first deformation surface are connected by a ball pair, and the second rod on the first deformation surface The other end of 10-2 is connected to one end of the third rod 10-3 on the first deformed surface through a ball pair, and the other end of the third rod 10-3 on the first deformed surface is ...

Abstract

The invention belongs to the field of aerospace and aviation, and specifically relates to a rhombic octahedron that can be scaled. It is characterized in that: the first deformation surface is connected with the third deformation surface through the first corner piece and the second corner piece, The third corner piece is connected to the fourth deformation surface, connected to the fifth deformation surface through the third corner piece and the fourth corner piece, connected to the third deformation surface through the fourth corner piece and the first corner piece; the second deformation surface is passed through The seventh corner piece and the eighth corner piece are connected to the third deformation surface, connected to the fourth deformation surface through the eighth corner piece and the fifth corner piece, connected to the fifth deformation surface through the fifth corner piece and the sixth corner piece, The sixth corner piece and the seventh corner piece are connected to the third deformation surface; the first corner piece is connected to the second, third, fourth, fifth, sixth, seventh and eighth corner pieces through the fixing piece. The invention has the advantages of convenient manipulation, high scaling degree and convenient storage.

Description

technical field [0001] The invention belongs to the field of aerospace and aviation, and in particular relates to a zoomable rhombic octahedron. Background technique [0002] Due to the limitations of rocket carrying capacity and space operations, it is often hoped that the device can be folded for easy storage, and then unfolded during operation, such as CN105523196B discloses a foldable polyhedron structure, but its unfolded Multiple components need to be controlled synchronously, which is not easy to manipulate. On this basis, the present invention uses the corner member as a bracket, so that the six deformation surfaces on it can be scaled as a whole only by controlling one of the corner members. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a method that is divided into two parts, and only one part can be rotated in one direction each time to realize the overall enlargement and reduction. ...
